Hello Dihiraj!

It sounds as if a bad ROM flash occurred, rendering the phone unbootable (AKA bricking it). Is this what happened? There are a variety of conditions that can result in a phone that won’t boot – any one of these conditions do not mean that the phone’s operating system was deleted though. Android handsets are designed specifically to prevent deletion of the core operating system files, unless you have root access and/or an unlocked bootloader.

If you did unlock it and did not perform a proper backup, then you may have some problems. First, Sony is pretty hostile toward users who unlock their bootloaders. It has been reported that Sony has refused to repair any phone with an unlocked bootloader.

Second, unless there’s already a custom recovery (I believe they refer to this as “update mode”) installed, the situation described means that the phone is unrecoverable, since you will have no means of flashing the original factory image or your backup image.

However, if you never unlocked the Xperia, then Sony might offer to restore the OS, especially if it’s still under warranty. I would definitely pursue this option if you haven’t unlocked the phone’s bootloader.

If you did unlock your phone and installed a custom recovery, made a backup, etc.., then consider some of the links below:

This tutorial explains how to backup your phone. It also (in the links section) contains links to everything you’d ever want to know about flashing, updating, etc… I highly suggest that you watch this video. There’s also a link in here about how to perform a flash and update.

Thanks dear to understand my problem, really i don not know exactly what happen . but i know what i did. I was trying to root my phone and i was trying this since last three days. i got all required files from XDA forum. I started flashing as per instruction, My flashing was done successfully then i realized that i forgot to unable usb debug but unfortunately that was too late, My data was already deleted from my phone.

Have you attempted to root the phone? Rooting can cause issues.

Try powering off the phone, either by removing the battery or waiting until the battery runs out of power. Then try turning the phone on while it’s plugged in to a power source. If the phone powers on without rebooting, the problem is likely not reoccuring. However, if the phone continues to reboot, I would guess that it’s due to improper permissions, a common issue with rooted phones. There are a lot of other potential problems, unfortunately.

The blinking screen means that the phone is at least physically probably OK. Unfortunately, if the software is damaged, then you may need to return the phone to the manufacturer.

If you rooted the phone and have already installed a custom recovery, then it’s a very simple matter – just reflash the stock ROM from the recovery. Usually the stock ROM can be downloaded. However, if you didn’t, then there might be issues.

You may want to try reading the ebook below, as it explains some of the basics of rooting:

Hello, I also have a problem with the Neo L, I haven’t attempted anything special with it, just daily use but I didnt do some app updates that I thought were useless(ie: facebook integration in the functionalities of the phone).

Now the phone wouldn’t start, when i press the power button it vibrates to confirm it is starting, but the sony logo never appears and the screen stays black.

I can see the back light behind the screen, but it just stays black. It has done this for 4 days, and would start normally one time out of five after I put out the battery, the sim card and the memory card(only 412mb left as free memory) but I didnt manage to start it at all today. Once the phone is on it can go smooth but it happened 2 times that I receive a call and realize my screen is black and i cannot even receive the call since the screen is not working.

Do you have any idea how to solve this since I cant even start the phone?
